Add a script which checks if contract addresses in src/versions.json are valid + add CI check

[Hugoo]

Adding a script which checks if the addresses set in the src/versions.json file are:

• deployed
• valid

by comparing the bytecode with the ones generated from typechain (npm run generate-types).

This would prevent us from copy/pasting wrong contract addresses, etc.

and allow an automated control in the CI.

As probably no one will take the time to check if the updated contracts addresses are valid.
